Precautions

US BOXED WARNINGS:
-ENDOMETRIAL CANCER: This drug is an estrogen agonist/antagonist with tissue selective effects; it has estrogen agonistic effects in the endometrium. There is a potential increased risk of endometrial cancer in a woman with a uterus who uses unopposed estrogens. Adequate diagnostic measures, including directed and random endometrial sampling when indicated, should be undertaken to rule out malignancy in postmenopausal women with undiagnosed persistent or recurring abnormal genital bleeding.
-CARDIOVASCULAR DISORDERS: In the clinical trials (duration of treatment up to 15 months), the incidence rates of thromboembolic and hemorrhagic stroke were 1.13 and 3.39 per thousand women years, respectively in ospemifene 60 mg treatment group and 3.15 and 0 with placebo. The incidence of DVT was 2.26 per thousand women years (2 reported cases) in the ospemifene 60 mg treatment group and 3.15 per thousand women years (1 reported case) with placebo. This drug should be prescribed for the shortest duration consistent with treatment goals and risks for the individual woman.
-There is a reported increased risk of stroke and deep vein thrombosis (DVT) in postmenopausal women (50 to 79 years of age) who received daily oral conjugated estrogen 0.625 mg alone therapy over 7.1 years as part of the Women's Health Initiative (WHI).

CONTRAINDICATIONS:
-Undiagnosed abnormal genital bleeding
-Known or suspected estrogen-dependent neoplasia
